Problem summary
**************************************************************** * USERS AFFECTED: Session Initiation Protocol (SIP) users of * * IBM WebSphere Application Server * * Feature Pack for Communications Enabled * * Applications (CEA) * **************************************************************** * PROBLEM DESCRIPTION: Sending an illegal UTF-8 character * * causes the SIP server to stop * * responding to future messages. * **************************************************************** * RECOMMENDATION: * **************************************************************** The problem occurs when sending an invalid SIP message to the application server, over a TCP or TLS connection. The message is invalid if its header contains a byte value larger than 127, which is not a UTF-8 character. This causes the SIP container to stop processing the message, and all messages that follow, over the same connection, including valid messages.
Problem conclusion
The problem is fixed in the SIP container. With this fix, the container drops the invalid message, and closes down the connection. If the invalid message is a request, the server replies to it with a 400 (Bad Request) response. This allows the client to create a new connection and send future messages over the new connection. The fix for this APAR is currently targeted for inclusion in fix pack 1.0.0.13 for the Feature Pack for Communications Enabled Applications.
